“…Banat et al [188] studied the potential applicability of VMD to separate methylene blue dye from aqueous solutions. In a more recent study VMD with PP membrane was used to concentrate solutions containing different amounts and types of dyes [185] while recovering pure water. The authors observed a decay in the permeate flux for all dyes studied, which was attributed to membrane fouling.…”

Membrane distillation is a process that utilizes differences in vapor pressure to permeate water through a macro-porous membrane and reject other non-volatile constituents present in the influent water. This review considers the fundamental heat and mass transfer processes in membrane distillation, recent advances in membrane technology, module configurations, and the applications and economics of membrane distillation, and identifies areas that may lead to technological improvements in membrane distillation as well as the application characteristics required for commercial deployment.

“…Production of high purity water is wellestablished with rejection factors of almost 100% of non-volatile compounds (Khayet & Matsuura, 2011). The MD process has been successfully studied for purification of waste waters of pharmaceutical (Ding et al, 2011) and textile (Criscuoli et al, 2008) industries as well as underground waters contaminated with heavy metals (Zolotarev et al, 1994) and sulfuric acid solutions (Tomaszewska, 2000). Very recently, the feasibility of applying membrane distillation process for recovering potable water from arsenic, uranium and fluoride contaminated brackish waters has been proposed (Yarlagadda et al, 2011).…”

“…Although there have been extensive studies on the application of MD for desalination, removal of organic matters in drinking water, treatment of wastewater and recovery of valuable components [5][6][7][8][9], the industrial implementation of MD is not yet feasible and significant advancements are still needed to reach the theoretical cost competitiveness and develop market share growth [10]. Membrane scaling in MD process is of particular importance, as scaling can alter membrane surface properties, change membrane pore structure, potentially lead to the wetting of membrane pores and ultimately cause a decline in membrane permeability [11].…”

Ultrasonic irradiation control of silica fouling during membrane distillation process

• Ultrasonic irradiation was introduced into membrane distillation process.• Influence of ultrasonic irradiation on silica fouling control was investigated.• Calcium ion would destroy silica colloid stability and aggravate membrane fouling.• Ultrasonic irradiation can mitigate silica fouling and maintain permeate flux. a b s t r a c t a r t i c l e i n f o Ultrasonic irradiation was introduced into membrane distillation process and the influence of ultrasonic irradiation on silica fouling control was investigated. A gradual decline of permeate flux during the concentration process of silica solution was observed due to the formation and deposition of colloidal polysilicic acid on the membrane surface. The PTFE hollow fiber membrane could maintain its mechanical properties and initial pore size distribution in the presence of ultrasonic irradiation. Ultrasonic wave brought significant mechanical and thermal effects, and generated powerful shock wave and microstreaming with high speed. The microstreaming, shock wave and acoustic vortex streaming stimulated the liquid-membrane interface continuously, therefore the membrane surface could be effectively kept clean and the permeate flux was hardly affected by the increasing of concentration factor. Due to the charge neutralization and compression of double charged layer induced by calcium ions, the silica colloid stability was eliminated and the colloids aggregated. A large amount of silica scaling was deposited on the membrane surface even at the beginning of concentration process. With ultrasonic irradiation, the permeate flux maintained stable and was enhanced by about 43%; the ultrasonic irradiation could effectively control silica fouling during membrane distillation.
